Achieve the purpose that deicing or snow melting.This method has the characteristics that simple and convenient, is at present both at home and abroad using more ice-melt snow method.According to
It counts the U.S. and is used for the deicing salt of road ice melting snow every year up to 13,000,000 tons.But it is largely easily caused for a long time using salt deicing salt
The salinization of soil of soil, deteriorates vegetation living environment, corrosion reinforcing bar, and road pavement causes permanent damage etc..And environmental protection newly developed
Type deicing salt, sodium chloride-containing, not smaller but expensive on environment and road influence, generally 3~4 times of common deicing salt.
(4) energy conversion melts ice and snow road.Energy conversion melt ice and snow road refer to by by solar energy, soil heat source,
Electric energy etc. is converted into the road of thermal energy.This method has clean energy, environmental-friendly, but energy utilization rate is low, and ice-melt snow effect is poor,
It is difficult to solve root problem.
